INSTALLATION 1. Determine the running positions of the reducer (Figure 3). Note that the reducer is supplied with 7 plugs; 5 around the sides for horizontal installations and 1 on each face for vertical installations. These plugs must be arranged relative to the running positions as follows: Horizontal Installations Install the magnetic drain plug in the hole closest to the bottom of the reducer. Throw away the tape that covers the filter/ventilation plug in shipment and install plug in topmost hole. Of the 3 remaining plugs on the sides of the reducer, the lowest one is the minimum oil level plug. Vertical Installations Install the filter/ventilation plug in the hole provided in the top face of the reducer housing. Use the hole in the bottom face for the magnetic drain plug. Of the 5 remaining holes on the sides of the reducer, use a plug in the upper housing half for the minimum oil level plug. motor mount. Tighten bolts to torque specified in Table 4. 3. Install motor, drive sheave and driven sheave so that driven sheave is as close to the reducer housing as practical. Install V-belt and tension with the four adjusting screws provided on the SCD Motor Mount. Install belt guard. Make required electrical connections for motor. WARNING: The user is responsible for comforming with the National Electrical Code and all other applicable local codes. Wiring practices, grounding, disconnects and overcurrent protection are of particular importance. Failure to observe these precautions could result in severe bodily injury or loss of life. 4. Because reducer is shipped without oil, it is necessary to add the proper amount before operating the drive. Use a high grade petroleum base, rust and oxidation inhibited (R & O) gear oil see lubrication tables. WARNING: To ensure that drive is not unexpectedly started, turn off and lock out or tag power source before proceeding. Failure to observe these precautions could result in bodily injury.

Use lifting tab to hoist screw conveyor drive into position. Slide shaft into screw and adapter over trough end studs. Only one set of adapter holes will fit over the trough end studs. If the mounted position of the screw conveyor varies more than 15º from any of the four horizontal mounting positions (Figure 1), an incorrect set of holes has been selected for coupling adapter to reducer. This can be corrected by removing adapter screws and rotating reducer to its proper position. Reinstall and tighten adapter screws to torque specified in Table 4. Install lockwashers and tighten nuts on trough end studs. Attach drive shaft to screw 2. Remove the three bolts from reducer housing required for mounting the SCD Motor Mount. Place the motor mount in position and install the three housing bolts supplied with the CAUTION: Unit is shipped without oil. Add proper amount of recommended lubricant before operating. Failure to observe these precautions could result in damage to, or destruction of, the equipment. LUBRICATION Under average industrial operating conditions, the lubricant should be changed every 2500 hours of operation or every six months, whichever occurs first. Drain reducer and flush with kerosene, clean magnetic drain plug, and refill to proper level with new lubricant. CAUTION: Too much oil will cause overheating and too little will result in gear failure. Check oil level regularly. CAUTION: Extreme pressure (EP) lubricants are not recommended for average operating conditions. Failure to observe these precautions could result in damage to, or destruction of, the equipment. Under extreme operating conditions, such as rapid rise and fall of temperatures, dust, dirt, chemical particles, chemical fumes, or oil sump temperatures above 200ºF, the oil should be changed every 1 to 3 months, depending on the severity of the 3

See last page of manual for lubricant viscosity classification equivalents. Special lubricants may be required for food and drug industry applications where contact with the product being manufactured may occur. Consult a lubrication manufacturer s representative for his recommendation. CAUTION: Do not use oils containing slippery additives such as graphite or molybdenum disulphide in the reducer when backstop is used. These additives will destroy sprag action. Failure to observe these precautions could result in damage to, or destruction of, the equipment. GUIDELINES FOR TORQUE-ARM REDUCER LONG-TERM STORAGE During periods of long storage, or when waiting for delivery or installation of other equipment, special care should be taken to protect a gear reducer to have it ready to be in the best condition when placed into service. By taking special precautions, problems such as seal leakage and reducer failure due to lack of lubrication, improper lubrication quantity, or contamination can be avoided. The following precautions will protect gear reducers during periods of extended storage: Preparation: 1. Drain the oil from the unit. Add a vapor phase corrosion inhibiting oil (VCI-105 oil by Daubert Chemical Co.) in accordance with Table 4. 2. Seal the unit air tight. Replace the vent plug with a standard pipe plug and wire the vent to the unit. 3. Cover the shaft extension with a waxy rust preventative compound that will keep oxygen away from the bare metal. (Non-Rust X-110 by Daubert Chemical Co. 4. The instruction manuals and lubrication tags are paper and must be kept dry. Either remove these documents and store them inside or cover the unit with a durable waterproof cover which can keep moisture away. 5. Protect the reducer from dust, moisture, and other contaminants by storing the unit in a dry area. 6. In damp environments, the reducer should be packed inside a moisture-proof container or an envelope of polyethelene containing a desiccant material. If the reducer is to be stored outdoors, cover the entire exterior with a rust preventative. 4
When Placing the Reducer Into Service: 1. Assemble the vent plug into the proper hole. 2. Clean the shaft extensions with petroleum solvents. 3. Fill the unit to the proper oil level using a recommended lubricant. VCI oil will not affect the new lubricant. 4. Follow the installation instructions provided in this manual.

REPLACEMENT OF PARTS Dodge is prepared to repair Screw Conveyor Drive speed reducers for customers who do not have the proper facilities or for those who desire factory service. However, if the customer has access to an arbor press, equipment for heating and shrinking bearings and gears on shafts, and the tools normally found in a maintenance department, the Screw Conveyor Drive speed reducer can easily be disassembled and reassembled by careful attention to the following instructions. Cleanliness is very important to prevent the introduction of dirt into the bearings and other parts of the reducer. The oil seals are of the rubbing type and considerable care should be exercised during disassembly or reassembly to avoid damage to the surfaces on which these seals rub. Any sharp edges on the input shaft or output hub should be covered with adhesive tape or paper before performing any work on the unit. Nicks and burrs on surfaces or the input shaft or output hub should be removed. ORDERING PARTS: When ordering parts for reducer, specify Screw Conveyor Drive size and serial number, part name, part number, and quantity. Parts that must be pressed from shafts or output hub should be removed before ordering parts. This assures that those parts, if damaged during pressing operation, will be replaced. It is recommended that when a pinion or gear is replaced, the mating gear or pinion be replaced also. This insures that the gear teeth will mesh properly. If the large gear on the output hub must be replaced, it is suggested that an output hub assembly, consisting of a gear assembled on an output hub, be ordered to secure an output hub with undamaged surfaces on which the oil seals rub. However, if the old output hub is to be used, carefully press the gear and bearing cones off. Thoroughly examine the area under the oil seals for scratches or any other damage resulting from the pressing operation. To prevent leakage at the oil seals, the rubbing area must be smooth. Replacements for the old oil seals should be ordered, due to the probability of these parts being damaged during disassembly. If replacing a bearing, output hub, or a shaft, it is advisable to order a set of shims for adjustment of bearings on the shaft assembly. If replacing a housing, a set of shims should be ordered for each shaft assembly because the adjustment of the bearings on each shaft assembly is affected. REMOVING SCREW CONVEYOR DRIVE FROM THE TROUGH END: Disconnect any electrical power to the drive. Drain lubricant from reducer. Uncouple drive shaft and screw. Remove nuts from trough end studs. Support drive by means of hoist and carefully pull unit away from trough end to slide drive shaft out of screw. DISASSEMBLY: 1. Remove retainer bolt, lockwasher, and shaft retainer from drive shaft. Pull drive shaft out of reducer from adapter side. Remove adapter. 2. Position reducer on its side and remove all bolts. Gently tap the output hub and input shaft with a soft hammer (rawhide, not lead hammer) to separate the housing halves. Open housing evenly to prevent damage to the parts inside. 3. Lift shaft, gear and bearing assemblies from housing. 4. Remove seals, seal carriers, and bearing cups from housing. 5. Clean all parts in solvent, inspect for damage, and coat with oil. 7 REASSEMBLY: 1. Output Hub Assembly: Heat gear to 325ºF to 350ºF to shrink onto hub. Heat bearings to 270ºF to 290ºF to shrink onto hub. Any injury to the hub surfaces where the oil seals rub will cause leakage, making it necessary to use a new hub. 2. Input Shaft Assembly: Shaft and pinion are integral. Press bearings on shaft. Press against inner (not outer) race of bearings. 3. Drive the two dowel pins into place in the right hand housing half. Apply RTV732 sealant to carriers for R.H. side (backstop side) of reducer. Install carriers and torque bolts per Table 5. 4. Place R.H. housing half on blocks to allow for protruding end of output hub. 5. Install bearing cups in right-hand housing half, making sure they are properly seated. 6. Mesh output hub gear and input pinion assembly together and set in place in housing. Set input shaft assembly in place in the housing. Make sure bearing rollers (cones) are properly seated in their cups. Set bearing cups for lefthand housing half in place on their rollers. 7. Clean housing flange surfaces on both halves, making sure not to nick or scratch flange face. Place a 1/8 bead of RTV732 sealant on flange face (make sure RTV is placed between bolt holes and inside of flange face). Place other housing half into position and tap with a soft hammer (rawhide, not lead hammer) until housing bolts can be used to draw housing halves together. Torque housing bolts per torque values listed in Table 5. 8. Place output hub seal carrier in position without shims and install two carrier screws diametrically opposed. Torque each screw to 25 in. lbs. Rotate the output hub to roll in the bearings and then torque each screw to 50 in. lbs. Again turn output hub to roll in the bearings. With a feeler or taper gage, measure the gap between the housing and the carrier flange. To determine the required shim thickness, take the average of the two feeler gage readings. Remove carrier and install the required shims plus.002. Install carrier with shims and torque bolts per Table 5. Rotate hub assembly, tap lightly with rawhide mallet on end of hub, while rotating, to ensure bearings are seated. Using a dial indicator check end play of hub bearings, endplay should be.001.003. Repeat this process as necessary to obtain proper end play. Place a 1/8 diameter bead of RTV732 sealant inside the carrier at the shim I.D. and install carrier on reducer housing. Torque carrier bolts to value shown in Table 5. 9. Using the same procedure as in step 8, adjust the input shaft bearings, except the axial end play should be.002 to.004. 10. Using gaskets or RTV732, install input shaft cover to righthand housing half. Install input and output seals. Extreme care should be used when installing seals to avoid damage due to contact with sharp edges on the input shaft or output hub. The possibility of damage and consequent oil leakage can be decreased by covering all sharp edges with tape prior to seal installation. Fill cavity between seal lips with grease. Seals should be pressed or tapped with a soft hammer evenly into place in the carrier, applying pressure only on the outer edge of the seals. A slight oil leakage at the seals may be evident during initial running, but should disappear unless seals have been damaged.
